Last week I went to get in my car and realized the power locks have gone out.(1993 300SE) Has anyone ever experienced or fixed this problem. It's not a fuse, checked everyone in the car. Also the handle that pops out of the trunk and the back-up assist antennas have quit working so I'm assuming these are all interconnected somehow. Are the locks on a W140 vacuum operated like the W126? Any help would be greatly appreciated. This car has so many electronics, i fear that once they begin to go out it's not long before it's dead.
